EDIT:Gmail now has an option to switch the standalone icons to text (Hurrah!), but this userstyle is still useful if you want both - keep the icons enabled on Gmail, and this userstyle will add the labels alongside the icons.

To use this style, install Firefox and Stylish. If you already have Stylish, make sure this site is allowed to run JavaScript.

Notes

First userstyle submitted (through frustration with the mystery meat), so it's quick and dirty. Not yet tested in all browsers, just Win Chrome and FF8 (as of 09/12/11). Only tested on desktop, no tablets or mobile devices.

If it works fine in you os/browser of choice let me know, or you want to send me any amends, you should be able to work out my email address :)
